My invention relates to dispensing devices and more particularly to faucets for dispensing, draughtbeer or the like. The object of my inventionis to produce a device that will dispense raw draught beer without the usual foam caused by carbonation and permitting the deposit of a .pre determined quantity of foam into the container onto the top of the raw beer.

Another object of my invention is to produce a device of the character described, that employs the customary attaching means to; the barrel or keg acting as-a container or supply reservoir for the beer, and permitting any conventional type of tapping mechanism.

A further object of my invention is to provide a faucet that has a three stage adjustment, thereby making it possible for the operator to manipulate the lever of the faucet much in the same manner as any conventional type of faucet.

Still another object of my invention is to .so

constructthe device as to permit its being cleaned without a great amount "of labor, there being comparatively few parts and all made readily accessible in their assembly.

Other and further objects of my-invention will p.

become more apparent as the description proceeds when taken in conjun-ction with the drawings in which 7 Figure 1 is a perspective side view of the tank showing the piping and faucet arrangement, and

illustrating the feed pipe and tubular coil within the tank in phantom,

similar characters of 'rf'r'ilc indicate corresppildifig parts throughout the several Views and referring to the same, the "characte "It TShO li I'S a tank of cylindrical sha e provides '9. conical cover 'I [attached to the tank 11),, by meanest a 'plurality of bolts 12, b If desired a gasket'not shown may be (placed between the tank In ami the cover I] an desirable may be employed f r retaining an'air tiglit seal. There is an inlet tube I a angularly disp sed throu'ghjthe wall or the tank. in a manner to permit the beer entering the tank II) from the keg or receptacle to assume 'a radial ath against the inner face or 'the wall 'ofthe tank to. and a vertical tube I3 I entering the bottom of 'the tank HL'to ipe'rmitfbee'r entering the tank I 0 to flow upward against the cover I l. The

cover I I is shown with an outlet tube 14 centrally disposedin its apex. The tube 14 leads' directly to a ffaucet assembly 1'5 and is providedwi'th connectingunitslli. Aspiralcoil 11 consisting of a tube smaller diameter than theyou-tlet tube 13 circlesaround the vertical tube and has its inlet within the tank I ll near its bottom as shown at 18 and the outlet end of the coil 11 terminates into a tube {9 which is disposed within the tube ll as shown inFigure 3 and extends with it to the faucet assembly 15. ;In Figure 4 is shown a connecting unit I I6 illustrating the manner which the tube 19 is disposed within the outer tube 14-. The connecting unit 16 consists of a member 20 engaging the outer tube 14 by means of a threaded portion at 23. An outer member zfthaving an inner thread engages the member 20 at 25 and acts as a clamping means to retain the member 22 in position. Obviously a gasket '01 washer "26, as shown may be employed to seal the contact 'of the two members 20: and-22. This same, construction may be 'employed as many connecting units as may be used in the proper installation of the device.-,

The member 20 is provided with an aperture 21 in its central portion through which the tube.

dual spout arrangement having two outlets 32 and 33 respectively, There is a revolving barrel 34 as shown in Figure 10. This barrel 34 is of cylindrical contour tapered smaller at one end and engages a tapered hole in the shell 29. The

of a screw 42 and inserted into an enclosure 43 recessed for the purpose into the shell 29 as shown.

through the coil I1 at its inlet I6 near the .bottom of the tank I and the horizontal spiral shape of the coil I! will cause raw, flat beer to be dispensed at the spout 33. When the lever 36 of the faucet I 5 is pushed rearward into the position -as shown at 49 in Figure 7 the port 45 will be aligned with-the aperture 46 and the spout 42 causing the foam which has accumulated at the top of the tank I0 to enter the tube I4 between 10 its inner face and the inner tube I9, and the pres- A port 44 is transversely disposed through the entire diameter of the barrel 34 and in proper alignment with the tube I9 and spout 33 'an'da port 45 also transversely disposed and in proper alignment with the ports 46 inthe spaces between tubes I4 and I9 and the spout 32. This port 45' is provided atits outlet with a plurality of aperture's 41 as shown in Figure 10. Both ports 44 and 45 are spaced in'direct'angula'r relation with one another and with the segmental section 40 so that either port 44 or 45 are in direct alignment with their respective supply ports and'out:

let ports. When the lever 36is' in 'a position as indicated at 48 shown in phantom in Figure 7 the port 44 in the barrel 34is in direct alignment with the .tube I9 and the spout 33 while when the lever 36 is in position as indicated at 49 in Figure 7 the port 45 is in direct alignment with the port 46 and the spout 32.

It is manifest to anyone familiar with the art that the member 20 may becon'structed with a separate insert incorporating the apertures 21 and 28 crime member 20 may be constructed integral as shown in Figure 4.

In operation the device functions as follows.

The entire device is connected to a' barrel or keg of beer in the conventional manner'by means of a tube leading to either the inlet tube I3 orrthe tube I3 of the tank' I 0. 'Ifthe former inlet is employed, the tube I3 will be closed'by'aconventional screw closurecap '(not shown) ,"and vice versa. The pressure applied to the barrel or keg containing the beer will causethe beer whenentering the tube I3 in the tank "III to fiowin acircular path against the wall within the cylindrical structure, and the foam caused by carbonation and pressure will find its way tothe top of the tank I0 immediately below the'cover II, and when the beer enters the tank In through the vertical tube I3 it will-flowupward against the inside of the cover II, causingthe foam to rise to the top of the tank I-0- immediately below the'cover II. With the lever 36 in a neutral-position,that is,

vertical as shown in Figure 7 the=faucet--I5 will as shown in the -position Min-Figure 7 the port 44 will properly align with the tube 19 and the spout 33. The beer in-the-tankluwill be forced sure will force the foam through the plurality of apertures 28 and the reduced apertures 41 in the barrel 34 and it will then be dispensed through the spout 32 of the faucet I5.

In this manner itis possible .to draw raw beer from the keg when the lever is in position as shown at 48 and any desired amount of foam may be placed on to the raw beer when the lever is placed in position as shown at 49 in Fig. 7.

"I do not desire however to befunderstood as confining myself to the said specific construction and relative arrangement of parts inasmuch as in future practice ofthe invention various changes and modifications may be made that fall within the scope of the appended claim.
